     Asthma common among Olympic athletes

    NEW YORK (Reuters Health) - More than one in five US athletes who took part in the 1998 Winter Olympics in Nagano, Japan, indicated a history of asthma or use of asthma medication, researchers report in the August issue of the Journal of Allergy and Clinical Immunology.

    These figures are higher than the prevalence of asthma in the general population. The disorder is estimated to affect between 4% to 7% of Americans.

    Dr. John M. Weiler, of the University of Iowa, Iowa City, and a colleague report that 44 (22.4%) athletes at the Games reported use of an asthma medication, a diagnosis of asthma or both. Altogether, 34 (17.4%) were considered to have active asthma.

    The highest prevalence of asthma-associated responses (60.7%) was seen in athletes taking part in Nordic combined, cross-country and short track events. The lowest (2.8%) was in the bobsled, biathlon, luge and ski jumping category. In those who participated in alpine, long track, figure skating, snow boarding or curling, the prevalence was 24%.

    The researchers conclude that asthma appears to have been more common in the 1998 Winter Games than in earlier Summer Games. They also point out that the difference in rates among sports “suggests that the environment in which exercise is performed is important in leading to a decrease in the amount of exercise required to trigger asthma.”

    The study findings “should reassure younger athletes who have asthma and who wish to be competitive athletes.” Dr. Weiler's group remarks., http://www.100md.com
